"Take me. It's dangerous to work with drones."

Launching Info:
For Windows with Java, a double click should suffice, and possibly the same with OS/X. As for Linux, depending on your distro, you may need to open terminal and try java -jar GRANT5.jar

Also, my source code is ugly and gross, so if enough people ask, I'll clean it up a bit and release it.
